The Backrooms is an internet creepypasta that got started in 2019. A simple post and picture on 4chan caught fire. It became stories, then a video game, then lots of video games. Then, it became live short videos that use lots of VCR like 80’s video quality effects.
Andy R Animations shows how he used free versions of Blender and Davinci to create some of the higher quality Backrooms videos. Definitely worth a look at the amazing things people can generate now using free tools.
